Very common in cultivated bottom lands, moist uplands and along gravelly banks. June-Aug. It spreads by both seeds and creeping underground stems and is often called wild morning-glory or pea vine. From the annual morning-glories above mentioned this and the next are told by the flowers having two slender stig- mas, whereas in them the 1 or 2 stigmas are globose or enlarged at tip. The bindweed often climbs up the stalks of corn or wheat and pulls them over, while potatoesand other low growing crops are liter- ally smothered by its vines and leaves. Its rootstocks bear numer- ous buds and if cut up any small piece with a' bud present will pro- duce a new plant. Three remedies are given for its eradication Fig. 74. (After Cox.) jn & Teeent bulMin * ^ (ft) Thorough cultivation every week or ten days between the spring and fall frosts, cutting out every piece o'f top growth that shows itself. (&) Pasturing with hogs which are very fond of the roots and rootstocks; the hogs of course should not have their noses ringed or slit, so that they may root deeply; if turned in just after the land is plowed the roots will be near the top and the hogs, if not furnished much other food, will go after them greedily, (c) Sowing the land to alfalfa, which not only tends to smother out the weed but by its necessary frequent cutting for hay serves in keeping down the top growth. The alfalfa should be followed by a cultivated crop to complete the work of eradication. 73: Convolvulus akveksis L. Field Bindweed. Corn-bind. (P. I. 1.)
